ROV Booting bug/problem

Hello there, I finished my dive with my ROV before 2 days

after some modifications and it worked normally. After finishing the dive as I disconnected the tether from my pc, the ROV started doing weird booting noises over and over again like booting and ready to connect. I can not upload video for some reason. I had a very small leak when I removed it from the water from the cap, but I don’t think it’s the case. When I opened it I found out I had forgotten to tighten the negative from the lights. I cleared everything proactively and I tightened the negative but happened the same again. I tried remove all the wires from the lights but and boot it again but it keep doing the same thing. Red, blue and Green light of raspberry light steadily. Also i checked the network connections and the status its connected, but still i can not connected either to blue local or qgroundcontrol.

Personally I believe it’s a bug problem on the raspberry pi software, but I open to your ideas about the case. Thanks in advance!
